CERN Sees Evidence of Ultra-Rare Particle Decay
Physicists working on CERN's LHCb experiment report evidence of a particle decay that is so rare it happens about once in ten billion times. The finding is described as a step closer to the zeptoverse, after a 42-year particle search.
Context
Context: CERN, near Geneva, runs the Large Hadron Collider, the world's largest particle accelerator. Rare decays are checked against the Standard Model, the current theory of particles, so any gap could hint at new physics.
